Unlockables

New Game +, new enemy types and rare cards.

Finish story mode once once, and you'll be able to start the game again from the start with all the cards you have. And you'll also encounter different opponents instead of generic black soldiers. Blue soldiers will give you exclusive rider cards you can't buy, red ones will give you rider cards from other series than the one you're actually on in story mode, yellow ones will give you rare support cards (yellow) and white ones seem to give you rider cards from a very specific and exclusive series different from the ones you get from blue soldiers.
